I have been having issues connecting my Ursa Mini Pro to a desktop PC using a bluetooth dongle which plugs into one of the USB ports. The camera gets successfully paired but then connection drops immediately between the two. Also I tried connecting to my laptop which has Windows 10 too and there I wasn't even able to pair the two devices. I have however successfully connected my Android phone to the camera and the connection was stable. Is this a known issue or I am missing some step when it comes to Windows 10? The bluetooth dongle that I am using is running on bluetooth v4, but it is backwards compatible to all of the previous software versions too.

I want to establish this connection between my PC and camera so that I can develop some software to control the camera remotely over bluetooth.

I would first check that your bluetooth dongle supports Bluetooth LE (Low Energy) protocol. It differs from the Bluetooth (classic) protocol. Almost all smartphones will support Bluetooth LE due to the lower power requirements, however many modern laptops will have dual mode receivers.
